Software projects, end to end. Mapped first, then built.
Last updated October 13, 2026
What is Mappstack?
Mappstack is a software services company. You hire it for whole software projects, end to end, new or existing, in any industry and at any size. Every system is mapped first, built from the map and checked against it, and every later change starts on the map.
What does Mappstack do?
Mappstack delivers whole software projects end to end, new or existing, in any industry. It also rescues apps built with AI and takes over as fractional CTO. When someone else builds, Mappstack checks the work. It connects systems and moves them off legacy. It puts AI to work with permissions, audit trails and human approval.
Who is Mappstack for?
Mappstack is for companies that need software built, rescued or changed and want to understand it after it ships. It takes on greenfield and brownfield projects in any industry and at any size.
How does Mappstack work?
Mappstack works in 3 steps: Map, Build and Evolve. Map: a new system is designed on the map before any code is written, and an existing system is mapped from its code. Build: people, AI agents or both build from the map, and every build is checked against it. Evolve: every change starts on the map, so the map and the system never drift apart.
What does Mappstack mean by a map?
A Mappstack map is a model of a software system that people and AI can read. It starts with the whole picture and zooms in only where needed. Each part is defined once, so every view of it updates together, and missing pieces show up in the design, not in production. The maps model software systems. They are not geographic maps.
What does an engagement with Mappstack look like?
A Mappstack engagement starts with a free call, then a fixed-price assessment, then fixed-scope phases you approve one at a time. Each engagement is tailored to the client, from a handover at launch to Mappstack running, hosting and maintaining the system. Work is remote with clients anywhere, with in-person visits in Australia, India and the EU when needed.
How does Mappstack pricing work?
Mappstack pricing follows the engagement: a free call, a fixed-price assessment, then fixed-scope phases approved one at a time. You decide on each phase before it starts.
Which stacks and industries does Mappstack work with?
Mappstack works in any industry and with any stack. Technology is chosen to fit the project, or the client's own stack is used when they require it. Projects start from proven building blocks, such as Stackure for passwordless auth, and from experience on past and present projects.
How does Mappstack use AI, and how is it checked?
Mappstack uses AI agents to build from the map, alone or alongside people, depending on the project. Every build is checked against the map and every change starts on the map, so the system stays explainable however it was written. When Mappstack puts AI to work in a client's business, it does so with permissions, audit trails and human approval.
Who does the work at Mappstack?
At Mappstack, people, AI agents or both do the work, chosen per project. Clients don't need to manage that unless they have a preference.
Can Mappstack take over an app built with AI?
Yes, Mappstack takes over apps built with AI. The app is mapped from its code first, so missing pieces show up before more is built, and every change after that starts on the map.
Can Mappstack be our fractional CTO?
Yes, Mappstack can take over as fractional CTO.
Can Mappstack check work that another team builds?
Yes, Mappstack checks the work against the map of the system when someone else builds.
